Getting Started.

The GB40 comes partially charged
out of the box and needs to be fully charged prior to use.
Carefully read and understand the vehicle owner’s manual
on specific precautions and recommended methods for
jump starting the vehicle. Make sure to determine the
voltage and chemistry of the battery by referring to your
battery owner’s manual prior to using this product. The
GB40 is for jump starting 12-volt lead-acid batteries only.

Connecting to the Battery.


Before connecting to the battery, verify that you have a 12-
volt lead-acid battery. The GB40 is not suitable for any other
type of battery. Identify the correct polarity of the battery
terminals on the battery. The positive battery terminal is
typically marked by these letters or symbol (POS,P,+).
The negative battery terminal is typically marked by these
letters or symbol (NEG,N,-). Do not make any connections
to the carburetor, fuel lines, or thin, sheet metal parts. The
below instructions are for a negative ground system (most
common). If your vehicle is a positive ground system (very
uncommon), follow the below instructions in reverse order.

1.) Connect the positive (red) HD battery clamp to the
positive (POS,P,+) battery terminal.

2.) Connect the negative (black) HD battery clamp to the

negative (NEG,N,-) battery terminal or vehicle chassis.
3.) When disconnecting, disconnect in the reverse
sequence, removing the negative first (or positive first
for positive ground systems).

Jump Starting.


1.) Verify the voltage and chemistry of the battery.
2.) Confirm the HD battery clamps are connected to
the correct polarity battery terminals.
3.) Connect the HD X Connector to the GB40.
4.) Make sure all of the vehicle’s power loads
(headlights, radio, air conditioning, etc.) are turned off
before attempting to jump start the vehicle.

5.) Press the Power Button to begin jump starting. All
LEDs will flash, indicating that all LEDs are properly
functioning. If you are properly connected to the
battery, the White Boost LED will illuminate. If the
battery clamps are connected in reverse, the Red Error
LED will illuminate. Reverse the connections to clear
this error and then the White Boost LED will illuminate.
The White Boost LED is illuminated, when the GB40 is
ready to jump start your vehicle.

6.) Try starting the vehicle. Most vehicles will
immediately start. Some vehicles may require the
GB40 to be connected for up to 30 seconds before
starting. If the vehicle does not start right away, wait
20-30 seconds and try again. Do not attempt more
than five (5) consecutive jump starts within a fifteen
(15) minute period. Allow the GB40 to rest for fifteen
(15) minutes before attempting to jump start the
vehicle again.
7.) Once you have started your vehicle, disconnect the
battery clamps, and remove the GB40.

Low Voltage Batteries & Manual Override


The GB40 is designed to jump start 12-volt lead-acid
batteries down to 2-volts. If your battery is below 2-volts,
the Boost LED will be “Off”. This is an indication that the
GB40 can not detect a battery.
If you need to jump start a battery below 2-volts there is a
Manual Override feature, which allows you to force “On” the
jump start function.

CAUTION.

USE THIS MODE WITH EXTREME CARE. THIS
MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY.
BOTH THE SPARK PROOF AND REVERSE POLARITY
PROTECTION FEATURES ARE DISABLED. PAY VERY
CLOSE ATTENTION TO THE POLARITY OF THE BATTERY
BEFORE USING THIS MODE. DO NOT ALLOW THE
POSITIVE AND NEGATIVE BATTERY CLAMPS TO TOUCH
OR CONNECT TO EACH OTHER AS THE PRODUCT
WILL GENERATE SPARKS. THIS MODE USES VERY
HIGH CURRENT (UP TO 1000 AMPS) THAT CAN CAUSE
SPARKS AND HIGH HEAT IF NOT USED PROPERLY. IF
YOU ARE UNSURE ABOUT USING THIS MODE, DO NOT
ATTEMPT AND SEEK PROFESSIONAL HELP.
Before using the Manual Override feature, make sure the
HD battery clamps are connected to the correct polarity
battery terminals and the HD X Connect is connected to
the GB40. To use the Manual Override feature, press and
hold the Manual Override Button (a red exclamation point
icon inside a red circle) for three (3) seconds. The White
Boost LED will flash “On” and “Off” indicating you have
successfully entered into Manual Override and it is ready to
jump start your vehicle. If connected in reverse polarity, the
Red Error LED will illuminate and the unit will not operate.

CAUTION:

POWER THE GB40 “OFF” BEFORE
DISCONNECTING THE BATTERY CLAMPS. THIS WILL
ENSURE YOUR SAFETY. REMEMBER BOTH THE
SPARK PROOF AND REVERSE POLARITY PROTECTION
